I guess I can disprove it, Bill.

I have circular saws that are solid HSS. I have circular saws that
are solid carbon or alloy steel. I don't recall seeing any bi-metal
circular saws, but that doesn't mean they don't exist.

I use only bi-metal circular saw blades. They're soft-steel centered
with carbide tips brazed on.
